摘要
俄罗斯东部Sikhote-Alin系统Kiselevka-Manoma增生杂岩层序下部具有以下放射虫组合特征(年龄由大到小):早期Pliensbachian到早期Toarcian，有Parahsuum izeenze, Bagotum maudense和Katroma clara。2. 早期白蚁属植物，有刚木和六翅目柠檬。3.中晚期到中早期的阿勒尼亚期，有格拉曼氏Paronaella grahamensis, Praeparvicingula gigantocornis和Hsuum exiguus。4. 早期-中期的阿勒尼亚?大黄、十字花菜和花椒。5. 晚期的阿勒尼亚人?海蛾属，海蛾属，海蛾属等。1. 6. 早-中巴荷西亚人，有贝尼德库尔塞拉和青叶菊。在该组合中描述了新种Olanda inflata Bragin, n. sp。研究的放射虫组合在亲和力上是特提斯的，这使得可以利用侏罗纪低纬度纬向放射虫尺度(Baumgartner et al.， 1995);Carter et al.， 2010)。Kiselevka-Manoma增生杂岩的燧石层序的总地层范围可估计为早侏罗世(pliensbachia -早Toarcian)-早白垩世(Barremian)。
EARLY AND MIDDLE JURASSIC (PLIENSBACHIAN TO BAJOCIAN) RADIOLARIA FROM CHERTS OF KISELEVKA-MANOMA ACCRETIONARY COMPLEX (AMUR RIVER, EASTERN RUSSIA)
The lower part of chert sequence of Kiselevka-Manoma accretionary complex, Sikhote-Alin system (Eastern Russia) is characterized by the following radiolarian assemblages (in ascending order of age): 1. Early Pliensbachian to early Toarcian with Parahsuum izeenze , Bagotum maudense and Katroma clara. 2. Early Toarcian with Bistarkum rigidium and Citriduma hexaptera. 3. Middle-late Toarcian to early-middle Aalenian with Paronaella grahamensis, Praeparvicingula gigantocornis and Hsuum exiguum. 4. Early-middle Aalenian with Parahsuum ? grande, Parahsuum cruciferum and Hsuum altile. 5. Late Aalenian with Parahsuum ? hiconocosta, Transhsuum hisuikyoense and Nassellaria gen. et sp. indet. 1. 6. Early-middle Bajocian with Sella beniderkoulensis and Emiluvia splendida. New species Olanda inflata Bragin, n. sp. is described from this assemblage. Studied radiolarian assemblages are Tethyan in affinity, which allows to utilize the low-latitude zonal radiolarian scales for the Jurassic (Baumgartner et al., 1995b; Carter et al., 2010). The total stratigraphic range of chert sequence of the Kiselevka-Manoma accretionary complex can be estimated as Early Jurassic (Pliensbachian-early Toarcian)-Early Cretaceous (Barremian).
期刊介绍：
Since 1976, Ofioliti provides an international forum for original contributions and reviews in the field of the geodynamics, petrology, geochemistry, biostratigraphy, stratigraphy, tectonics and paleogeography applied to ophiolitic terrains and modern oceanic lithosphere, including their sedimentary cover. Studies of topics such as geodynamics of the mantle, the evolution of orogens including ophiolites and paleoceanography are also welcome
